CANOPENER.

opener, the object in View being to provide a hand operated device whichis especially convenient and effective for the purpose stated, enablinga clean cutof any desired length to be-made either in the top or bottomof a can or in and around the side wall of the can.

While the improved device is adapted for opening small cans it isespecially adapted for opening cans of large sizes, as the work may bedone with ease and rapidity, leaving a clean edged cut.

Another advantage of the device resides in the fact that the cut is madeoutwardly so as to eject the small particles of tin or other materialwhich are removed from the edges of the cutduring the cutting operation.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as herein described,illustrated and claimed.

In the accompanying drawing:

Figure 1 is a perspective view of the opener.

Fig. 2 is a plan view of the body of the device showing the formation ofthe blades and other parts thereof.

Fig. 3 is a plan view of the handle with the fulcrum piece attached.

Fig. 4 is a cross-section on the line H of Fig. 3, showing the fulcrumpiece in elevation.

The improved opener comprises a loop handle 1, or the equivalentthereof, composed of a strip of metal or other suitable material ofanysuitable length bent or formed into the form shown in Fig. 3.

2 designates-the body of 'the opener which is formed of sheet steel orother suitable material and fastened between the parallelportions 3 ofthe handle by means- Specification of Letters Patent.

which is preferably serrated as shown at 8. The'fulcrum piece 3 isformedwith a notch or slot 9 to straddle one of the blades of the deviceas shown.

The body 2 comprises a blade 10 of ogeeshape and another blade 11 whichis curvilinear or C-shape. In addition to the blades 10 and 11, there isa short pointed combination can and bottle opening-tang 12, the outerextremity of which is pointed as shown at 13, adapted for opening canscontaining liquid only, milk or oil, for example, in which casefrequently a small opening is desired. In using point 13, with is placedin a practically horizontal position, point 13 being driven through the.

end wall of the can, adjacent to the edge of the latter. After the pointhas been inserted through the can, the opener is pressed firmly downwardand the handle is moved in a circular direction, thus causing point 13to act as a pivot, and in this manner the opening may be made any sizeup to the width of tlie'tang. Said tang also has adjacent to the basethereof, a lifting point or hook 14 adapted to engage the underside ofthe rim of a bottle cap for example, and pry said cap off the bottle,the fulcrum piece 7 resting upon the cap :u ooint diametrically o positethat point engaged by the hook 1 1. I

The blade 10 is formed with a reversely extending can puncturing-point15, and the blade 11 is likewise formed with a reversely extending canpuncturing point 16, the points 15 and 16 being used to primarily 1puncture or penetrate the can and thereby enable the respective bladesto be used for finishing the cutting operation.

In using the blade 10, with the can in a the can adjacent to the edgethereof and about one-half to one inch infront of the seam extendinglongitudinally of the side wall of the can. After the point 15 is wellinserted, the handle is ressed downwardly or toward the can there ycausing blade 10 to cut backwardly in the side wall of the can as far asthe seam and. parallel to adjacent end thereof. The blade 10 is thenmoved inwardly as far as it will go and an upward cut is formed byraising the handle of-the device. The operation just referred to is t tothe edge of the latter. After the point has been inserted through thecan, the

handle is pressed firmly downward, thus causing the blade 11 to cutbackwardly. The device is then restored to a substantially uprightposition and the handle pressed firmly downward while the fulcrum pieceis held in engagement with the edge of. the can. This causes the blade11 to form an upward and forward cut. The operation just referred to iscontinued, always moving the blade forwardly to the end of the previouscut, after each operation until the top of the can has been completelyremoved. After the primary puncturing process has been effected, it willbe observed that the opener always cuts upwardly or outwardly, therebygiving a tendency to eject or to throw out the loose particles of metalor other material.

The blade 11 is provided with a serrated portion 19 on the convex sideextending from a point near and below the junction of blades v 10 and11, to a point below fulcrum piece 7, and near the upper cuttingextremity of blade 11, which acts as fulcrum for blade 10, and restsupon a point above and in front of where the cutting edge of blade 10engages with the can, and prevents slipping during the cuttingoperation.

I claim The combination of a handle, and a canopening member fastenedthereto and embodying two cutting blades one of which is ogee shapedlying and disposed laterally of the handle and formed with a reverselycurved and pointed end portion, the other blade being C-shaped andprojecting from the end of the handle and also having a reversely curvedand pointed end portion, the first named blade having a concaved cuttingedge and the second named blade having a convex cutting edge opposedthereto and serrated for a portion of its length, said cutting edgesbeing in spaced relation to each other and the end portion of the firstnamed blade being extended beyond the end of the handle in overlappingbut spaced relation to the second named blade.

In testimony whereof I affix my signature.
